PROBLEM TO BE SOLVED: To provide a vacuum pump fixing structure capable of preferably restricting a deformation of a valve stopper through striking against a cam housing when the vacuum pump is assembled to a cam housing.SOLUTION: A vacuum pump 10 coupled to a cam housing has a valve stopper 19 at an end surface of its cam housing so as to protrude out of a coupling surface with the cam housing. The coupling part with the cam housing at such a vacuum pump 10 as above is provided with a protrusion 20 of which protruding amount from the coupling surface is larger than a protruding amount of the valve stopper 19 from the coupling surface. |
